I have a 2003 h.o.6 speed. Truck has 116k on it. Recent 150hp injectors, 6.7 cp3 upgrade, fass 150 among.other things. When accelerating up to or past 1800 rpms, the truck surges and or misses. When trying to keep a steady pedal at cruising speed at or above 1800 rpms and 15k rail pressure, it starts to surge and you can watch the rail gauges surge then the fuel pressure gauges proceeds to do the same. But when at full throttle it runs fine. I have ran the scanner on it, no codes, and have tried a different cp3 regulator. Also have ran with and without ssr to no avail. Does the same thing. Could someone please help me?!
